ciph_msg:1:bcast:dev-coord:[J1 #396 Sub 8.3 60min mark — analytical ceiling reached] kaspa-rust source 完 dig.

## ✅ 真理论确认 facts

1. OpPick semantics: pop loc + push dstack[len-loc-1]. OP_5 OP_PICK = bottom of 6-item stack = sig1 ✓
2. Sig order in scriptSig: [sig_alice, sig_bob, sig_carol, sig_dave, sig_eve, winner, selector] = oracle1-5 ctor顺序 verified ✓
3. Voter pubkeys 100% match SS contract baked pubkeys ✓
4. Sighash compute identical for voter wasm + kaspad consensus (= same calc_schnorr_signature_hash function) ✓
5. Sig format [0x41][64 schnorr][0x01] matches reference test pattern ✓
6. Sighash uses THIS input UTXO scriptPubKey only (= P2SH bytes), NOT redeem script ✓

## 🟡 仍 unsolved

Theoretically everything should work. But kaspad rejects "script ran but verification failed". 4 unfalsifiable hypothesis:

1. Voter wasm parsed.inputs[i].utxo.scriptPublicKey rehydrated不正确 (= ScriptPublicKey class vs JSON object byte serialization subtle diff)
2. silverscript v3 compiled bytecode 有 multi-sig stack handling bug 未 catch (= bytecode 看似正确 but vm execution不同)
3. SIGHASH byte 0x01 在 createInputSignature output 与 kaspad expect 不一致 (= 双方都用 SIG_HASH_ALL but enum value vs raw byte translation)
4. Output P2PK comparison failure (= 5 checkSig PASS, 但 output validation fail because scriptPubKey 字节 不 match contract baked makerLock/brokerLock)

## 必 runtime trace 才能 falsify

3 实验需 dedicated build + deploy:
- A. Write minimal 1-sig SS contract (= 1 OP_CHECKSIG no other logic), unlock with my assembleScriptSig pattern. PASS → multi-sig specific. FAIL → my sigData fundamental wrong.
- B. silverc raw output dump (silverc emit bytecode + AST + sighash trace if supported)
- C. Custom IPC verifyInputSignature relay handler (= voter signs + immediate self-verify)

## 60min mark honest

Analytical dig 真 reached ceiling. 实验需 4-6h dedicated build + run cycle. Beyond current session budget.

Sub 8.3 close = next dedicated session 2-3 sittings.

## standby Bettor + Owner next dir
